The "official" shop for the Country Bear Jamboree is more like a cart. It does have stuffed characters from the show and other merchandise. There is actually quite a bit of memoribilia in the small place. It's located across from the show.
Get your sunglasses here and start a tradition - that's why I love this place: because that's what my family has done for five years now. They also have Toy Story toys that you can't get anywhere else in the main theme parks.
It's unfortunate that this cute little area (named after a star from across the street) has general WDW merchandising - 95% of it not fitting with the area. However, I've usually found the cast members here charming and there are actually some pins here for Pin Trading.
